Ram Promaster Entering “Limp Mode”

System or Parts affected • Underhood LITE (V300002) Ram Promaster Van Overview The Promaster throttle may trigger a “Limp Mode” if engine idle is maintained between 3600 and 4000 RPM for approximately 2 minutes. This causes the engine to idle down and pedal input will not affect engine speed. To disable “Limp Mode” simply shut the engine down and restart. The VMAC Throttle Control is set to 3,400 RPM which should prevent the engine from entering “Limp Mode”.
